isNotEmpty → bool

Whether there is at least one key/value pair in the map.

no setter, override

keys → Iterable<K>

The keys of this Map.

no setter, override

length → int

no setter, inherited

unregisteredValue → Map<K, V>

Read the current value without calling register

no setter, inherited

value ↔ Map<K, V>

Methods

addAll(Map<K, V> other) → void

Adds all key/value pairs of other to this map.

override

addEntries(Iterable<MapEntry<K, V>> newEntries) → void

Adds all key/value pairs of newEntries to this map.

override

cast<RK, RV>() → Map<RK, RV>

Provides a view of this map as having RK keys and RV instances, if necessary.

override

clear() → void

Removes all entries from the map.

override

containsKey(Object? key) → bool

Whether this map contains the given key.

override

containsValue(Object? value) → bool

Whether this map contains the given value.

override

copyValue() → Map<K, V>

Copy the value for update emission

override

forEach(void action(K key, V value)) → void

Applies action to each key/value pair of the map.

override

internalSetValue(Map<K, V> value) → void

Internal setter for _value. Should only be used in Rx extensions and never externally. Does not notify.

inherited

map<K2, V2>(MapEntry<K2, V2> convert(K key, V value)) → Map<K2, V2>

Returns a new map where all entries of this map are transformed by the given convert function.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notify() → void

Notify listeners with the current value

inherited

notifyIfChanged<U>(U transform()) → U

Notify if transform changed the value such that shouldNotify returns true

inherited

notifyWithValue(Map<K, V> value) → void

Notify listeners with the given value

inherited

putIfAbsent(K key, V ifAbsent()) → V

Look up the value of key, or add a new entry if it isn't there.

override

register() → void

Register with the current zone's RxRegistrar if it exists

inherited

remove(Object? key) → V?

Removes key and its associated value, if present, from the map.

override

removeWhere(bool test(K key, V value)) → void

Removes all entries of this map that satisfy the given test.

override

replaceAll(Map<K, V> elements) → void

Convenience method to replace all current elements with elements

run(RxAction action, {bool notify = true}) → bool

Run action with registration and notifications disabled. Will notify after action is completed if notify is true and the child implementation decides a notification should be sent.

inherited

shouldNotify(Map<K, V> oldValue) → bool

Check if the value has changed

override

toString() → String

A string representation of this object.

inherited

update(K key, V update(V value), {V ifAbsent()?}) → V

Updates the value for the provided key.

override

updateAll(V update(K key, V value)) → void

Updates all values.

override

Operators

operator ==(Object other) → bool

Returns true if both RxValue values are equal

inherited

operator [](Object? key) → V?

The value for the given key, or null if key is not in the map.

override

operator []=(K key, V value) → void

Associates the key with the given value.
